Embodiment Construction

[0013] Please refer to FIG. 1 , which is a circuit block diagram of a specific embodiment of a multi-purpose switch circuit. A multi-purpose switch 10 operated by the user is an automatic reset switch. As shown in Figure 1, it is a double-contact automatic reset switch. Circuit 30, a delay circuit 50 and an electronic device main body 60 are all connected to a node A; a contact 110 (for convenience of description, hereinafter referred to as "left contact 110") of the double contact automatic reset switch is suspended ( 1) or be connected to a high potential (not shown), and the other contact 120 (hereinafter referred to as "right contact 120") is connected to a low potential, such as ground. In other embodiments, the multi-purpose switch 10 can also be a push-type automatic reset switch, one contact of the push-type automatic reset switch is grounded, and the other contact is connected to node A.

[0014] The electronic device main body 60 performs various actions according t...

Abstract

A multi-function switching circuit includes an automatic reset switch with diversified operations, a power supply, a switch control circuit, a switch circuit, and a delay circuit, and the said electronic device main-body has a power switch port, and a replacement port; the said switch circuit is placed among the power supply, the switch circuit and the delay circuit; the said switch control circuit accepts the control of the automatic reset switch, and controls the switch circuit according to the automatic reset switch; the said switch circuit connects / disconnects the linkage between the delay circuit and the power supply according to the control of the switch control circuit. According to the number functioned by the automatic reset switch, the said multi-function switch circuit determines open or close of the electronic device main power supply, and according to the time length functioned by the automatic reset switch, it triggers the delay circuit to produce replacement signal to replace the electronic device main-body, in order to produce the one-switch multi-function effect, and reduce the electric devices volume.

Description

【Technical field】 [0001] The invention relates to a switch circuit, in particular to a multi-purpose switch circuit. 【Background technique】 [0002] An intelligent electronic device is often composed of hardware and software to complete many functions. Some of these functions are automatically triggered by the internal system of the electronic device, and most of them are executed by sending instructions from the user. If the user sends instructions to execute, it must provide the user with external operations. Devices, such as buttons / knob switches, etc., if each button / knob corresponds to only one operating function of the system, then more and more buttons / knobs are needed to trigger the electronic device as the functions of electronic devices are becoming more and more integrated All functions, which will inevitably affect the volume of electronic devices, run counter to the portable type advocated today. 【Content of invention】 [0003] In view of this, a multi-purpos...
